Let me preface this by saying that I will not ask you to reveal yourself if you are on any of these sites.

I've registered on Otaku Booty and will be registering on Geek 2 Geek, and Sweet on Geeks. I am, like so many others, hoping to find a girl geek to spend some time with. Have any of you, male or female, used any of these sites? What's been your experiences with them? Worth it? No?
